KB18 - Compact drilling rig with wire core drilling technology
The KB18 is a compact crawler-mounted drilling rig that, in addition to classic dry, flushing, and hollow auger drilling methods, particularly excels with its wire-core drilling technology. This makes it especially suitable for geological explorations, geotechnical investigations, and projects requiring precise core extraction and clean sample handling.
Compared to smaller machines, the KB18 offers greater structural stability, a stable working platform, and the ability to perform wireline core drilling economically in the field without relying on large exploration equipment. At the same time, it remains mobile, easy to transport, and technically straightforward, making it an attractive option for small and medium-sized exploration programs.
The KB18 is therefore a solution for users who need precise core samples, stable running performance and flexible drilling methods – without the expense of a full-fledged large-scale exploration rig.
